This is a very high current cell.
I do not test it fully, as can be seen in the specifications above it can be discharged down to 2.0 volt, but it looks like 2.5 volt is the preferred value.

The label is not from Sony but applied by Akkuteile.de

Very impressive tracking between the cells, it is difficult to see that there is curves for two cells.
According to the datasheet for the cell the temperature can raise more than 50°C during a 20A discharge.

Conclusion

This is a very good high current battery, it has fairly high capacity and can deliver a lot of current.
